I can't speak for those not running a VPN Client, but I really think OpenVPN has something to do with it. After a reboot, the VPN traffic is speedy and getting good rates... after a week or so, it drastically slows down and am only pulling about 5Mbps up and down... the CPU seems to be pegged at almost 100% trying to sustain this traffic. At this point, the GUI is extremely sluggish to the point where it's timing out in the browser. This, I believe, leads to the GUI just becoming completely non-responsive, and am just catching a glimpse as to what happens prior. Took some screenshots of my router running 6 days and 12hrs. Very light traffic... CPU is pegged. I'm not familiar with ways to troubleshoot this, but running the TOP command shows the VPN client hogging the most for the very little traffic it is handling.I'll keep you guys posted, but it may be a few weeks before I have any news to report. Happy chasing!
